The following general-purpose registers are provided:
General-purpose registers: An 8-bit register for storing data
The general-purpose registers are 8 bits and located in the register banks of the memory. One bank contains
eight registers. Up to a total of 8 banks can be used on the MB89181 (RAM 128
× 8 bits) and a total of 16 banks
can be used on the MB89182/183 (RAM 256
× 8 bits). The bank currently in use is indicated by the register
bank pointer (RP).
Note: The number of register banks that can be used varies with the RAM size.
